Often people who work for startups work for dysfunctional organizations. Mature F500 Orgs also have lots of internal dysfunction. Most places are not "SGI"-type organizations. Also what we see in public is different from what people see on the inside.
Much of what see in public is the agitators being angry. Also, some regular staff will get caught up in the maelstrom, that's understood. But, if you are part of the org that emerges out of this difficult time, you may find it rewarding.
I think much of the difficulty is attributable to people having been used to the previous management style not being able to adapt to the new one and conservatively wanting to retain the familiar, their cozy fireplace in the winter. Elon, is like, arouse, we have work to do!
